T0 all wwm it may concern:

Be it known that I SAMUEL D. MADDIN, a citizen of the United States, and aresident of Miamisburg, in the county of Montgomery and State et Ohio, have invented certain new and nseful Improvements in Harvesters, of Which the following is a specification.

My invention relates to a harvestingmachine constructed, as fully described hereinafter, to support the frame by two wheels withont obstructing either end of the platform, permit the binder to deliver the grain direct ly from the end of the platform without lifting it over the wheel, and prevent any nndue draft or drag of either end of the machine.

The invention further consists of certain details of construction wherebythe operations of the machine are facilitated.

In the drawings, Figure 1 is a plan view of the machine partly in section Fig. 2 is an end elevation. Fig. 3 is a detached view showing the connections With the drivingwheels.

The frame of the machine is constructed to support the platiorm and also the binder,when the latter is used, and is supported by two wheels, B B, one or both of which are drivingwheels, the wheel B being at the front of the main body of the machine, and the platform O supported thereby, and the wheel B being arranged diagonally in respect to the first at the rear of the main frame and in rear of the cuttenbar. The pole D extends from the frame preferably about midway between the two wheels. By this arrangement the wheels, without being at both ends of the machine, are so far apart as to afford substantial bearings at separated points of the machine, yet not so far that the tongne will occupy a position at any material distance from the draft-center, so that the detrimental side draft, which resnlts from putting one of the driving- Wheels much farther from the pole than the other, is avoided. One of the chief advantages of this arrangement, however, is the exposure of both ends of the frame, so that a binding meehanisin arranged on the platform 0 at W between the supporting-wheels can deliver the grain directly from the end Y xjvith out the necessity of elevating the same over the supporting-wheel. The binder at V is a1- ranged upon the platform 0 at the side nea1 est the -wheels, and occupies a position direct ly npon the platform, which is near the gronnd, and the condnctingcanvas E, passing round the nsual rollers, a a, delivers the grain to a position adjacent to the binder, and the sheaves fall from the binder behind the wheel B Withont being lifted over. the same.

I have indicatcd the position of the binder by the letter W, but have not otherwise illustrated the samc, as any of the nsual forms of binding-machines may be employed, and further illustration is unnecessary.

When a binder is not employed, the arrangement described secnres a good side clelivery without setting the cutter deviee far forward of the wheel and overbalancing the other parts. A partly-hollow rock-shaft, Z), passes through a long box, 0, secured to the platform, and has seeured to it two arms, I) and f. The arm 6 supports the journal 2)" of the wheel B, and the armf extends forward outside of the wheel B. wo parallel arms, I) and b, are hung loosely to a spindle, k, which extends through the shaft I), said arms oarrying at their forward ends the axle of the wheel B.

In connection with the main frame A, thus consisting of two jointed parts, (the parts b b f, connected with the wheel B, and the parts b b, connected with the wheel B,) I employ deviees of any suitable character, whereby the two parts 7) b" can be brought into horizontal plane or at any required angle t0 eaeh other, so as to thereby elevate or depress the rock-shaft I) and the platform and parts connected thereto. A lever, E, pivoted at X to a bracket supported on the forward axle, is connected at the forward end to the forward end of the arm f, so that by bearing npon the rear end of said lever E the arm f and rockshaft b are raised, the journal 6 of the wheel B being the fulcrum, and the arms b b b* brought more nearly into line or toward the position shown hy dotted limes 5 5, Fig. 2. This lever E may support the drivers seat F, so that the weight of the driver may be utilized in raising the frame. To seeure the parts in position, a lever, V, is pivoted to one side V of the arm I), and is connected by a link, 6,

to the arm f, and arranged so that the driver may look said lever With a look-plate, 23, or detach it therefrom. The pole D is pivoted as near the roek-shait 7) as possible, and the platform is tilted to any desired angle by means of a lever, G, pivotecl to the pole, and connected to the platform by a rod, i. (See dotted limes, Fig. 2.) Suitable catches seeure the lever, as is common in this class Of machines.

By arranging the wheels near together and about equidistant from the pole, one behind and the other near the end of the platform, I am enabled to employ both for driving, as there is practically little more d raft on one than on the other. Any suitable gear and connections may be employed between the wheels and the drivingpulley or wheel U, from'which the cutters, rollers, reel, binder, &c., derive their rnovements in any ordinary manner. A bevel-wheel, S, and a toothed wheel, T, eaeh connected to the spindle k by a baeking ratehet meehanism eonsisting of a spring-pawl, t, upon the wheel, and a ratehet,

u, are secured to the spindle, upon whieh spindle is also the driving-wheel .U, the shaft 12 being bent round the wheels U and T, as shown. The wheel S gears with a pinion, S, on a shaft, m, driven by bevel-gear from the wheel B, and the wheel T is driven from a toothed wheel, n,

\ on the wheel B, through the medium of an idlewheel, p, earried on a stud projeeting from the arm If. This arrangement insures the revolution of the spindle 75 and its drivingwheel U, whichever of the wheels B B may turn forward, while the backward movement of either wheel has no efleet upon the spindle.

Without limiting myself to the precise construction and arrangement of parts shown, I claim 1. The combination, in aharvester, of a main frame supporting the operating parts, a driving-wheel supporting said frame at one side, and aseeond driving-wheel si1pporting the opposite side of said frame, but arranged diagonally to the first and pack of and between the vertical planes of the ends of the cutter-bar, substantially as set forth.

2. The combination of the main frame, platform, cutter-bar, supporting-wheel at one side and ahead of the platform, and a second wheel at the rear ofthe platform and cutter-bar and between the vertical planes of the ends .of the cutter-bar, substantially as set forth.

3. In a harvesting-maehine,the eombination of the main frame,the platform,and the wheels arranged to support the frame, one at the side but forward of the platform, and the other at the rear,between the ends of the platform, t0 leaveboth ends and the entire front of the platform unobstrueted, for the purpose set forth.

4. The combination,in aharvester,of a platform, the eutting apparatus supported by the platform,the binding apparatus,also supported by the platform at one end, and two main supporting and driving wheels, one arranged forward of the binder and the other wheel.be hind the cutter, substantially as specified.

5. The eombination of the main frame, the supporting driving-wheels, one at the front and the other at the rear, the platform carrying the cutter-bar and extending in front and on eaeh side of the rear wheel, and the tongue connected to the frame between the two Wh eels, substantially as described.

6. The combination of the main frame, the platform carrying the cutter and binder, and two driving-wheels arranged at opposite sides,

one at the rear and the other at the front of said main frame, substantially as deseribed.

7. The combination of the frame having one arm projecting fOrward and another extending backward, the arms loosely connected together by a wheel supporting eaeh arm,atilt ing platform bang to the frame,and appliances for raising and lowering the same, substantially as deseribed.

8. The combination of the platform, the jointed frame supported by wheels arranged diaonally, one at the front and one at the rear of the frame, and appliances for raising and lowering the frame at the joint, for the purpose set forth.

9. The combination,with the jointed frame supported by wheels, of a lever for lifting and lowering the same on a fulcrum eoinciding With the journal of the rear wheel, and a seat for the driver supported on the front-aXle and connected to said lever, substantially as de sCribed.

10. The combination,with the jointed'platform, lever f, lever E, and seat F, of the look- -ng-lever V, substantially as described.

In testimony whereof I have signed my name to this speeification in the presence of two S1lb*' scribing witnesses.
